Despite a strong rally in the last three vote tallies, Lisa Calderón failed to overtake Kelly Brough and secure a spot in the runoff election for the next mayor of Denver.

Mike Johnston, meanwhile, maintained his lead in a dominant performance that persisted through the last two days. 

So far, Johnston holds 24.45% of the vote, with Brough at 20% and Calderón at 18%.   

Denver mayor's race: Vote tally as of 2 p.m. April 6

This graph shows the unofficial tally of the mayor's race in Denver as of 2 p.m. on April 6. (Graph from Denver Clerk and Recorder's Office.)  

The last tally at 2 p.m. Thursday, which counted roughly 22,000 votes, gave Calderón 5,208 votes, compared to Brough's 3,525.

But it was insufficient to put Calderón in second place.

In order to overtake Brough, she needed to win 38% of the 23,000 ballots left to count — which also means outperforming Johnston.

Instead, Calderón received 24% of the latest tally, while Brough maintained a 16% share. 

In the last tally, Calderon came short by about 3,200 votes.

On Twitter, Calderón acknowledged not making the runoff election and thanked her supporters for believing in her vision of Denver. She said her campaign “did more with less.”

Though her run was unsuccessful, Calderon said she will campaign with other like-minded candidates, such as Shontel Lewis, Candi CdeBaca and Shannon Hoffman, who are running for council districts 8, 9 and 10, respectively.

The Denver Clerk and Recorder's Office said roughly 2,400 votes are left to be counted. These are ballots that need a “cure” or clarification about a discrepancy or other adjudication.
